Autumn's arrival in the Northern Hemisphere on Sept. 22 swept in significant news of progress for the global fight against COVID-19. A protein-based COVID-19 vaccine candidate from Clover Biopharmaceuticals Ltd. and Dynavax Technologies Corp. appeared wholly effective in preventing severe disease and hospitalization, sending Dynavax shares (NASDAQ:DVAX) climbing 26.5% to close at $18.79 on Sept. 22. In another study of Gilead Sciences Inc.'s Veklury (remdesivir), the drug significantly reduced hospitalization in high-risk patients with COVID-19. Meanwhile, governments and companies continued to expand efforts to supply new vaccines and therapeutics against the disease even as efforts continued far and wide to evaluate the efficacy of new and emerging candidates in both categories.
